Molecular beam mass spectrometry

  "id": "MLC-T-CHM-007480",
  "term": "Molecular beam mass spectrometry",
  "field": "Chemistry",
  "definition": "A form of mass spectrometry in which the gas to be analyzed is drawn through a small orifice, often by supersonic expansion, and shaped into a narrow beam of neutral molecules that travels into the ion source. Sampling this way stops collisions and reactions in the beam, so short-lived radicals and other reactive intermediates are detected as they existed in the original system. Flame and combustion studies are the classic application.",
